I was about to go to bed ________ there was a knock at the door.

A. while B. when C. as D. suddenly

I’ve often wondered how exactly sleep, or lack of it, can have such an awful effect on our bodies and, guess what, how much we sleep switches good genes(基因) on and had genes off.

In the first half of 2013, the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes. Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook. However, each cell only “reads” the part of this handbook it needs at any given moment.

Can sleep affect how a gene reads instructions? It’s a question asked by Professor Derk-Jan Dijk at the University of Surrey. He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours.

Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights. The results were rather surprising. Several hundred genes changed in the amount they were being used, including some that are linked to heart disease, cancer, and Type 2 diabetes. Genes to do with cell repair and replacement were used much less.

Sleep restriction(six and a half to seven hours a night) changed 380 genes. Of these, 220 genes were down regulated (their power was increased). Those affected included body-clock genes which are linked to diabetes(糖尿病). One of the most downgraded genes is that which has a role in controlling insulin(胰岛素) and is linked to diabetes and insomnia(失眠). The most upgraded gene is linked to heart disease.

So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little.

The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes.

1.What kind of relation is directly discussed in the passage?

A. Sleeping hours and changes of genes.

B. Sleeping hours and diseases.

C. Changes of genes and diseases.

D. Genes and health.

2.What can we learn about Professor Derk-Jan Kijk’s experiment?

A. The experiment was carried out to find the answer to how genes affect sleep.

B. The experiment took a period of more than two weeks to reach a conclusion.

C. His volunteers were divided into two groups with two different sleeping patterns.

D. Blood samples of the volunteers were checked afterwards to decide how many genes changed in sleeping.

3.Which of the following may be concluded from the passage?

A. The experiment was performed at the University of Surrey in early 2013.

B. Body-clock genes are associated with heart disease, cancer and Type 2 diabetes.

C. Sleep restrictions may contribute to disease like diabetes, insomnia, and heart disease.

D. 7.5－8 hours’ sleep pattern makes little difference compared with 6.5－7 hours’ sleep pattern.

4.Which of the following can be inferred from the findings of the sleep research?

A. When there is a sleep restriction, genes to do with cell repair and replacement function less.

B. In a sleep, several hundred genes change in the amount. The more changes, the worse results.

C. When genes are up regulated, they do good to health; when genes are down regulated , they do harm to health.

D. Eight hours of sleep a day can be beneficial to our health in that it looks after our genes.

House Sitting

In many countries of the world people do what is called house sitting. It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel. After people retire, they might buy a van and travel all over the country. 1.

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy. House sitters might have to care for pets. Also, quite a few people have swimming pools in their back yard and they need cleaning. 2. I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

3. There are websites where you find the advertisements by people who want to travel, and by replying to the advertisement, you can make arrangements to go and look after their home.

There are some requirements to be a house sitter. You must be a trusted person, so that the home owner knows you will not steal anything. You must be able to go when the house owner wants you to go, so you need lots of free time. 4. You need to be good with pets, able to care for cats and dogs, or other pets they may have.

Some house sitting jobs are just for a few days or a couple of weeks while the house owners have a short holiday. Sometimes it is for much longer. We have had one house sit for six months, while the home owner travelled to Europe.

5. Then you can travel to many different countries and stay there. One of the important things to get is references from the home owners where you have stayed. A reference is a written letter to say that you are trustworthy and have looked after their home well. You can show these letters to possible house sitting jobs and they know you will do a good job.

A. I have done house sitting many times.

B. Thousands of people do this all the time.

C. It is also possible to do house sitting in other countries.

D. Generally you have many opportunities to get a house sitting job.

E. You must take a little care over what your description says about you.

F. This is an international house sitting service for all city and country areas.

G. You must have a good car, so you can travel to different parts of the country.

Hong Kong, a city of seven million—and growing fast. By the year 2050 Hong Kong’s population will almost double. Where will these people live?

There’s only one place to go—up. Fast forward 50 years．This is the tallest man-made structure on the planet. Its name：Millennium Tower. It would stand twice as tall as anything built before. Over 60 thousand people would live or work here. Millennium’s designers think it represents the best solution for the coming population explosion.

It would cost ten billion dollars and consume more building materials than any single nation could produce. David Nelson, one of Millennium’s key designers, said：“It would be a massive project and a world project. But to actually realize it, resources would have to come from all over the globe. The challenge and the motivation for doing it would be to realize one of the world’s largest and most complex construction projects.”

Millennium would be more complex than anything ever built. So its builders won’t know for sure the building is safe until it’s up, and they can’t afford to make an error. Massive earthquakes have brought down entire cities in this part of the world. Can Millennium’s designers make it immune to these quakes of the earth?

For Millennium, like all the other buildings, safety is just one concern among many. It will need to be a home, one that welcomes people in. Getting people into the building and making sure they have a great experience well be what makes Millennium successful, but how to do it? For the design team, the secret was to bring all the elements of city life within. Cafes and restaurants, theatres and stores would provide entertainment. Health clubs, even schools and medical clinics would also serve the towers’ residents.

Millennium’s designers have proven something. Things that seem impossible today, might just become reality tomorrow. The engineering problems have, for the most part, already been solved. Our achievements are limited only by our imaginations.

1.Why did the designers decide to build Millennium?

A．Because they wanted to build the world’s most complex building.

B．Because Hong Kong’s population will greatly increase.

C．Because Hong Kong is developing fast as an international city.

D．Because it can bring huge profit after it is put to use.

2.What is TRUE about the project?

A．It will be completed in the year 2050.

B．It can accommodate all the residents in Hong Kong.

C．It is designed by designers from all over the globe.

D．It has to be strong enough to stand earthquakes.

3.The success of Millennium mainly relies on _______.

A．how many resources will be used

B．how many nations will work together

C．whether people can enjoy their life in it

D．whether it is safe for people to live in

4.How does the writer develop this passage?

A．By providing descriptions. B．By using figures.

C．By giving examples. D．By analyzing causes.

The national parks are very important for the protection of these wild animals，which would _____ run the risk of becoming dying out．

A．therefore B．instead

C．otherwise D．anyhow

Everyone, from homeless people to billionaires, is likely to be influenced by stress; there’s simply no way to avoid it.1.Here are five powerful tips for ways to kill stress in almost any situation.

4.

Since you are never going to remove 100 percent of the stress in your life, one of the best things you can do is let it be one of your motivations. This is what stress is designed to do, after all.

Watch a Funny Video

Here is a simple and practical tip: watch a funny video on YouTube. Research shows that seeing something amusing activates the part of the brain that produces calm physiological(生理的) responses. This can lead to less anxiety and more happiness.
